Description

Technical Field

[0001] The present disclosure relates to the technical field of mobility scooters, and in particular to a mobility scooter integrated seat chassis device and a mobility scooter. Background Art

[0002] Elderly mobility scooters have been widely used in the daily travel of the elderly. However, the distance between the seat and the handlebars of the current elderly mobility scooters is a fixed distance designed at the factory, which cannot meet the needs of users of different body shapes. For example, for users with a larger body shape, the space will seem too small when using the narrow seat, and the user experience will be poor. In addition, it will be difficult to get off the vehicle due to the small seat space. For another example, for users with a smaller body shape, the distance between the seat and the handlebars is too large, and they cannot easily grasp the handlebars, which poses certain safety hazards. In addition, the seats of existing elderly mobility scooters are mostly fixed to the chassis and cannot be rotated left and right, which makes it difficult for users with limited mobility to get on and off the vehicle.

[0003] In addition, the armrests of the existing elderly scooter seats are mostly not adjustable horizontally. The distance between the left and right armrests is designed to be a fixed distance, which cannot meet the use needs of different users. Utility Model Content

[0049] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0050] According to an embodiment of the present disclosure, the utility model provides a scooter integrated seat chassis device. Figure 1-10 As shown, a mobility scooter integrated seat chassis device includes a seat front and rear adjustment assembly 100, which includes:

[0051] The sliding assembly 110 has a first mounting surface 111 and a second mounting surface 112 which are arranged perpendicularly to each other. The first mounting surface 111 is used for mounting the seat, and the second mounting surface 112 is provided with a first mounting hole 113;

[0052] The first base 120 is provided with a travel hole 121 and a plurality of first limit holes 122 along its length direction. The travel hole 121 is connected to the first mounting hole 113 through a first connecting member 123 so that the first mounting hole 113 can move back and forth along the travel hole 121;

[0053] The first locking member 130 is installed on the second mounting surface 112, and the first locking member 130 has a retractable first locking portion; the first locking member 130 is configured so that when the first locking portion is located in the first limiting hole 122, the sliding assembly 110 is in a locked state, and when the first locking portion is out of the first limiting hole 122, the sliding assembly 110 can move back and forth along the travel hole 121.

[0054] For example, the first connecting member 123 may be a shoulder bolt, the first end of which is connected to the second mounting surface 112, and the second end of which passes through the first mounting hole 113 and the travel hole 121 in sequence, thereby connecting the first mounting hole 113 and the travel hole 121. Preferably, the second end of the shoulder bolt may be threadedly connected to a nut or a nut, so that the shoulder bolt is restricted on the first mounting hole 113 and the travel hole 121, so that the first mounting hole 113 can move back and forth on the travel hole 121 with the shoulder bolt.

[0055] For example, a plurality of travel holes 121 may be provided. To save space on the first base, the travel hole 121 and the first limit hole 122 may be opened on the first base 120 in an upper and lower position. To facilitate the processing and connection of the first mounting hole, the travel hole and the first limit hole, the first base 120 may be a shell structure with a cavity inside. Since the sliding assembly needs to be moved back and forth along the first base for adjustment, the first base 120 should be relatively long in length so that the sliding assembly can adjust the movement stroke in a larger range.

[0056] The present invention discloses a scooter integrated seat chassis device, which is provided with a seat front and rear adjustment assembly 100 composed of a sliding assembly 110, a first base 120 and a first locking member 130, and can effectively adjust the distance between the seat 400 on the sliding assembly 110 and the handlebars, so as to meet the needs of users of different body shapes, and enable users to adjust conveniently as needed, thereby improving user satisfaction. Moreover, the structure is simple, time-saving and labor-saving.

[0057] In one embodiment, Figure 2-3 , Figure 6-7 As shown, the first locking member 130 includes a first locking inner rod 131 and a first return elastic member 132, the first locking inner rod 131 is formed as a first locking portion, and the first return elastic member 132 has an elastic force; the first end of the first locking inner rod 131 is fixedly connected to the first end of the first return elastic member 132, and the second end of the first return elastic member 132 is connected to the second mounting surface 112, wherein when the first return elastic member 132 is in a free state or a compressed state, the second end of the first locking inner rod 131 is located in the first limiting hole 122, and when the first return elastic member 132 is in a stretched state, the second end of the first locking inner rod 131 is disengaged from the first limiting hole 122.

[0058] For example, the first locking inner rod 131 is generally in a rod-shaped structure. The first reset elastic member 132 has elastic force. When it is in a free state or a compressed state (the so-called free state means that it is neither compressed nor stretched), the second end of the first locking inner rod 131 is located in the second limiting hole 122, so that the sliding assembly 110 and the first base 120 are in a locked state. When the first reset elastic member 132 is stretched and in a stretched state, the second end of the first locking inner rod 131 is disengaged from the first limiting hole 122, so that the sliding assembly 110 and the first base 120 are in an unlocked state. At this time, the sliding assembly 110 can drive the seat 400 thereon to move back and forth along the travel hole 121 on the first base 120, so as to adjust the distance between the seat 400 on the sliding assembly 110 and the handlebar.

[0059] Further, such as Figure 2-3As shown, the first locking member 130 further includes a first outer tube 133, which is sleeved on the outside of the first locking inner rod 131 and the first resetting elastic member 132, and the second end of the first resetting elastic member 132 is connected to the second mounting surface 112 through the first outer tube 133. Specifically, the second end of the first resetting elastic member 132 is connected to the first outer tube 133, and the first outer tube 133 is connected to the second mounting surface 112.

[0060] like Figure 3 As shown, a first threaded hole 1121 is formed on the second mounting surface 112, and the first outer tube 133 has an external thread and is threadedly connected to the first threaded hole 1121 through the external thread, so that the second end of the first locking inner rod 131 in the first outer tube 133 can be movably passed through the first threaded hole 1121. Therefore, when the first reset elastic member 132 is in a free state or a compressed state, the second end of the first locking inner rod 131 can be movably passed through the first threaded hole and the second end is located in the first limiting hole.

[0061] For example, Figure 3 As shown, the free end of the first outer tube 133 is also sleeved with a first handle 134, which is movably sleeved on the first outer tube 133, and the first handle 134 is detachably connected to the first end of the first locking inner rod 131, for example, the first end of the first locking inner rod 131 is clamped on the first handle 134. Therefore, when the user needs to adjust the distance between the seat 400 and the handlebar, the first handle 134 can be pulled outward to drive the first locking inner rod 131 to disengage from the first limiting hole 122, so that the sliding assembly 110 and the first base 120 are in an unlocked state, and at this time, the sliding assembly 110 drives the seat 400 to move along the travel hole 121 of the first base 120, so as to achieve the purpose of adjusting the distance between the seat 400 and the handlebar.

[0062] For example, the first return elastic member 132 has elastic force, and therefore, the first return elastic member 132 includes but is not limited to a first return spring.

[0063] In one embodiment, the first locking member 130 can also be a first threaded member, which is threadedly connected to the second mounting surface 112; the first threaded member forms a first locking portion, and the first threaded member is rotated so that its end is located in the first limiting hole or disengaged from the first limiting hole, so that the sliding assembly can be switched back and forth between the locked state and the unlocked state. Specifically, for example, the first threaded member can be threadedly connected to the first threaded hole 1121 formed on the second mounting surface 112, and the first threaded member can be rotated so that its end is located on the first limiting hole, so that the sliding assembly is in a locked state; when the sliding assembly needs to be unlocked, the first threaded member is rotated in the opposite direction so that its end is disengaged from the first limiting hole. The first threaded member can be a screw, a bolt, or a stud.

[0064] In one embodiment, the sliding assembly 110 includes:

[0065] A horizontally arranged seat support plate 114, the upper surface of which forms a first mounting surface 111, and the seat support plate 114 is used to mount the seat 400;

[0066] The sliding member 115 has two parallel mounting plates 1151 , and the mounting plates 1151 are vertically fixedly connected to the seat support plate 114 , and the mounting plates 1151 form the second mounting surface 112 .

[0067] Therefore, when the first locking member 130 is composed of the first locking inner rod, the first reset elastic member and the first outer tube 133, the first threaded hole 1121 can be opened on one of the mounting plates 1151, the first outer tube 133 is threadedly connected to the first threaded hole 1121 and the first locking inner rod 131 is located in the first limiting hole 122 after the second end passes through the first threaded hole 1121 when the first reset spring is in a free state or a compressed state.

[0068] In order to facilitate the installation and fixation of the sliding member 115 and the seat support plate 114, the sliding member 115 can be a long U-shaped member, the length of which is adapted to the length of the first base 120, and the two side wings of the U-shaped member serve as two mounting plates 1151, and the top surface of the U-shaped member is welded and fixed to the lower surface of the seat support plate 114, so that the seat support plate 114 and the sliding member 115 form a sliding assembly 110 with a fixed structure. Preferably, the sliding assembly 110 is an integrally formed member composed of the seat support plate 114 and the sliding member 115. The integrally formed member is easy to process and has a high load-bearing capacity.

[0069] In one embodiment, Figure 1-10 As shown, the integrated seat chassis device of the mobility scooter of the present application includes a rotation adjustment assembly 200, which includes:

[0070] A second base 220, the second base 220 is vertically rotatably mounted on the first base 120 and the first end of the second base 220 is located in the inner cavity of the first base 120, and the first end of the second base 220 is provided with a plurality of second limiting holes 221 along its circumferential direction;

[0071] The second locking member 210 is installed on the first base 120. The second locking member 210 has a retractable second locking portion. The second locking member 210 is configured so that when the second locking portion is located in the second limiting hole 221, the first base 120 is in a locked state; when the second locking portion is out of the second limiting hole 221, the first base 120 can drive the sliding assembly 110 to rotate around the second base 220.

[0072] The present application sets up a rotation adjustment assembly 200 composed of a second locking member 210 and a second base 220, so that the first base 120, the sliding assembly 110 and the seat 400 thereon can be rotated around the second base 220, so that the seat can be rotated left and right, making it convenient for users to get on and off the vehicle.

[0073] For example, the second locking member 210 includes a second locking inner rod 211 and a second reset elastic member 212, the second locking inner rod 211 forms the second locking portion, and the second reset elastic member 212 has an elastic force; the first end of the second locking inner rod 211 is fixedly connected to the first end of the second reset elastic member 212, and the second end of the second reset elastic member 212 is connected to the first base 120, wherein when the second reset elastic member 212 is in a free state or a compressed state, the second end of the second locking inner rod 211 is located in the second limiting hole 221, and when the second reset elastic member 212 is in a stretched state, the second end of the second locking inner rod 211 is disengaged from the second limiting hole 221.

[0074] Furthermore, the second locking member 210 further includes a second outer tube 213, which is sleeved on the second locking inner rod 211 and the second reset elastic member 212, and the second end of the second reset elastic member 212 is connected to the first base 120 through the second outer tube 213. Specifically, a second threaded hole 1201 is formed on the first base 120, and the second outer tube 213 is threadedly connected to the second threaded hole 1201 through an external thread at the end thereof, so that the second locking inner rod 211 inside the second outer tube 213 can freely move through the second threaded hole 1201. By pulling the second locking inner rod 211 outward, the second end portion of the second locking inner rod 211 can be disengaged from the second limiting hole 221, so that the rotation adjustment assembly 200 is in an adjustable state. Therefore, the first base 120, the sliding assembly 110 and the seat thereon can be rotated left and right around the second base 220. When it is rotated to a suitable position, the second locking inner rod 211 is released so that the second end portion of the second locking inner rod 211 is re-restricted in the second limiting hole 221, thereby locking the rotation adjustment assembly 200.

[0075] For example, Figure 3As shown, the free end of the second outer tube 213 is also sleeved with a second handle 214, which is movably sleeved on the second outer tube 213, and the second handle 214 is detachably connected to the first end of the second locking inner rod 211, for example, the first end of the second locking inner rod 211 is clamped on the second handle 214. Therefore, when the user needs to rotate the seat left and right, the second handle 214 can be pulled outward to drive the second locking inner rod 211 to disengage from the second limiting hole 221, so that the second base and the first base are in an unlocked state, and the first base, the sliding assembly and the seat are rotated at this time, so that the seat rotates around the second base, thereby achieving the purpose of rotating the seat left and right. Since the sliding assembly can move back and forth along the first base, it is recommended that the sliding assembly and the first base are in a locked state when the seat needs to be adjusted to rotate left and right.

[0076] For example, the second locking inner rod 211 can be a long rod-shaped structure. The second reset elastic member 212 includes but is not limited to a second reset spring. The second base 220 is a circular tubular structure with a cavity inside, or the second base 220 can also be a disc structure with a plurality of second limiting holes 221 formed thereon.

[0077] For example, a limiting shaft 222 is disposed on the first end of the second base 220, and both ends of the limiting shaft 222 protrude from the second base 220 to limit the second base 220 on the first base 120, thereby preventing the second base from falling off the first base.

[0078] For example, the rotation connection between the second base 220 and the first base 120 can be achieved in the following manner:

[0079] like Figure 3-4 As shown, a support 223 is provided on the second base 220, and an assembly hole 1202 adapted to the second base 220 is provided on the first base 120. The first base 120 is mounted on the support 223 through the assembly hole 1202, so that the first base 120 can rotate around the second base 220. Further, in order to prevent the first base from detaching from the second base, the limiting shaft 222 is provided at the first end of the second base 220, so that the first base is limited between the limiting shaft 222 and the support 223 in the vertical direction. Furthermore, in order to reduce the friction resistance generated when the first base rotates around the second base, a plastic part is provided on the assembly hole between the first base and the second base to reduce the friction when the two bases produce relative motion.

[0080] Alternatively, a bearing may be provided between the second base 220 and the first base 120. The bearing may be provided to achieve relative rotation between the two. Alternatively, the presently known technology may be used to achieve that the first base 120 can rotate around the second base 220, which will not be described in detail here.

[0081] Of course, it is also possible that when the integrated seat chassis device of the scooter of the present application only needs to achieve the purpose of rotating the seat left and right without adjusting the distance between the seat and the handlebar, the first base 120 and the sliding assembly 110 can be set as a fixed connection mode, and more preferably, the two can be set as an integral part. Or only the first base 120 is set without the sliding assembly 110. Therefore, the first base 120 has a cavity inside, and the first base 120 is formed with a first mounting surface 111 and a second mounting surface 112 that are vertically arranged. Specifically, for example, when the first base 120 and the sliding assembly 110 are fixed structures, the seat support plate 114 on the sliding assembly 110 forms the first mounting surface 111 for mounting the seat. The mounting plate 1151 on the sliding assembly 110 and / or the side plate on the first base 120 form the second mounting surface 112 for mounting the second locking member 210 and the armrest spacing adjustment assembly 300. When the sliding assembly 110 is not provided and only the first base 120 is provided, the top plate and the side plate of the first base 120 are respectively formed as the first mounting surface and the second mounting surface. Of course, in order to fix the seat more stably, the first base 120 is more inclined to fix the seat support plate 114 with a slightly larger area to fix the seat more stably. The installation positions of the second locking member 210 and the armrest spacing adjustment assembly 300 can be adaptively adjusted according to actual production needs.

[0082] In one embodiment, for example, the second locking member 210 can also be a second threaded member, which is threadedly connected to the first base 220, and the second threaded member forms a second locking portion. By rotating the second threaded member so that its end is located in the second limiting hole or disengaged from the second limiting hole, the first base can be switched back and forth between the locked state and the unlocked state. Specifically, the second threaded member can be threadedly connected to the second threaded hole 1201 formed on the first base 120, and by rotating the second threaded member, its end can be located on the second limiting hole, so that the first base is in a locked state; when it is necessary to unlock the first base, the second threaded member is rotated in the opposite direction so that its end is disengaged from the second limiting hole. The second threaded member can be a screw, a bolt or a stud.

[0083] The integrated seat chassis device for a mobility scooter of the present application can be applied to a mobility scooter. Therefore, during actual installation, if Fig.11 As shown, the support platform 223 can be fixedly connected to the connecting assembly 500 of the mobility scooter to enable the first base, the sliding assembly and the seat thereon to rotate relative to the mobility scooter.

[0084] In one embodiment, Figure 1-3 , Fig. 9 As shown, the integrated seat chassis device of the mobility scooter of the present application further includes an armrest spacing adjustment assembly 300, which includes an armrest assembly 310 and an armrest connecting sleeve 320;

[0085] The armrest assembly 310 is connected to the second mounting surface 112 of the sliding assembly 110 through an armrest connecting sleeve 320. The armrest connecting sleeve 320 includes a first sleeve 321 and a second sleeve 322 sleeved outside the first sleeve.

[0086] A third locking member 330 is installed on the armrest connecting sleeve 320, and the third locking member 330 is configured so that when in an unlocked state, the first sleeve 321 and the second sleeve 322 can move relatively, and when in a locked state, the first sleeve 321 and the second sleeve 322 can be relatively fixed.

[0087] Specific examples include Figure 3 As shown, the armrest assembly 310 is fixedly connected to the first end of the first sleeve 321, the first sleeve 321 is arranged in the second sleeve 322, and the first end of the second sleeve 322 is fixedly connected to the second mounting surface 112 of the sliding assembly 110. Therefore, when the distance between the armrest assemblies needs to be adjusted, the third locking member 330 can be placed in an unlocked state, and the armrest assembly can be pulled outward to move the first sleeve outward along the second sleeve until it moves to a suitable position, and then the third locking member 330 is placed in a locked state to relatively fix the two sleeves. In this way, the use requirements of users of different body shapes for the distance between the armrest assemblies can be met.

[0088] For example, the third locking member 330 is a third threaded member, which can be a bolt, a stud or a screw. There can be multiple third locking members 330. The third locking member 330 is threadedly connected to the third threaded hole 3221 formed on the second sleeve 322. When the third locking member needs to be in an unlocked state, the third locking member 330 can be rotated to disengage its end from the pressure on the first sleeve 321. When the two sleeves need to be in a fixed state, the third locking member 330 can be rotated to press its end against the first sleeve 321, thereby achieving the purpose of relative fixation of the two sleeves.

[0089] Alternatively, the third locking member 330 is a spring knob having a telescopic end. The spring knob is threadedly connected to a third threaded hole 3221 formed on the second sleeve 322 and the telescopic end can abut against the first sleeve 321 .
